The high-temperature resistant screw conveyor is optimized for conveying high-temperature materials ≤950℃. Its main body is made of high-temperature stainless steel and ceramic structures, the screw blades are made of high-temperature resistant stainless steel, and the bearings are high-temperature resistant or ceramic ones. The chain transmission between the drive and the main machine reduces heat transfer, ensuring long-term stable operation in high-temperature environments.
The GWL-SF high-temperature resistant screw conveyor is an improved version of the tubular screw conveyor, suitable for conveying high-temperature materials with a temperature typically below 950°C. The main body of the conveyor adopts a design combining high-temperature stainless steel and ceramic structures; the screw blades are made of high-temperature resistant stainless steel; the bearings use high-temperature resistant bearings or ceramic bearings; and the drive unit is connected to the main machine via chain/gear transmission to reduce heat transfer. These features ensure the conveyor can operate reliably in high-temperature material environments for long periods.
